Bring two cups of water to boil in a saucepan, and add the whole barley grains. Simmer for 55 minutes, so that the water soaks into the grains and makes them very soft and chewy. Drain away any excess liquid and set the warm grains aside for a moment.

Grilled mushrooms

Melt the butter in a frying pan and add the whole mushrooms and finely chopped garlic. Fry for five minutes.
